.APPARATUS FOR EXTRACTNG- LIQUIDS.

Application led August 24, 1921. Serial No. 494,766.

To all .whom t may concern:

Be it known that I, ABRAM S. KIRSH- NER, residing at Philadelphia, county o-f Philadelphia, and State of Pennsylvania, a

citizen of the United States, have invented certain new and useful Improvements in Apparatus for Extracting Liquids, of which the following is a specification. v

This invention relates to apparatus for )lo extracting liquid from any material, such, for example, as oil from cotton-seed, and the object of the invention lis to provide means for creating two kinds of mechanical forces upon the material, one a series of compressions, a hammering or percussive pressure'to crush, mascerate and compress the more solid portion of the material; and the other a centrifugal motion, to throw off the liquid expressed from the pulpy constituents.

ln the illustrated and preferred embodiment of my invention, the material treated, such as cotton-seed and the like, is subjected to the rapid series of compressions successively delivered by mechanical means that will be described, while the entire mass is simultaneously acted upon by centrifugal force, generated for example by the rapid rotation of the parts carrying the material being separated.

lin the accompanying drawings:

Fig. 1 is a vertical section through the entire machine;

Fig. 2 is a similar view of the upper portion of the machine on an enlarged scale;

Fig. 3 is a fragmentary sectional view of the lower portion of the machine enlarged, with certain parts in elevation;

Fig. 4 is a fragmentary side elevation of the lower portion of the machine;

lFi s. 5 and 6 are end and top Views respect1vely of the details.

Referring to the drawings, the letter A designates an outside casing, which may be of any desired form, but is shownin the drawings as made vup of several` castings, which I shall designate the base casting 1,

the top castin 2, the hopper casting 3, and

the bearing-p ate 4, all of which parts are T3 held secured -together by screws 5, thus. making'it possible to easily dismantle the maclnne and put it together, .or to gain access to the mechanism. The numeral 6 is a worm shaft, held sta- 'tionary by the squared lower end 7 in a hole in the bottom of the cup 8, and the latter is held in place in an orifice 9. in lthe casting 1 by screws 10. A removable plate 11 closes the lower end of the cup 8. rlhe upper end of the worm-shaft 6 has a worm 12 thereon. a hollow stem 14, which surrounds and confines the worm shaft 6, as shown in 1. Surrounding the lower end of the hollow stem 14 is a sleeve 15. A bevel-gear 16 is secured to this sleeve 15, and this is driven by a bevel-gear 17 on the horizontal driveshaft 18.

Journaled in the sleeve 15 are the two crankshafts 19, and secured on these crankshafts are worm-gears 20, which mesh with the worm 12. As the drive-shaft 18 revolves, it transmits motion through the gears 16 and 17 to the sleeve 15, and by turning them the two crank-shafts 19 are rotated by reason of the worm-gears 20 meshing with the stationary centrally located worm 12. These crank-shafts have the connecting-rods 21 connected therewith, and these connecting rods extend to the collar 22 .to which the connecting-rods are. connected by pins 23. A key 24 extends across through the slots 25 in the hollow stem 14, and through holes 26 in the collar 22, and is secured by a screw 27 to a central shaft 28, which not only rotates with the sleeve 15 and collar 22 but also reciprocates with the rotation of the crank-shafts 19.

The cotton-seed or other material is fed down through a hopper 29 at thetop of the machine into the receiving-'chamber 30 below, and the reciprocation of the shaftv 28 imparts a compressing effect to the head 31 through toggles 32, thus feeding and compressing the material and forcing it up through compression chamber 33 between the outer wall of the receptacle 30 and the inner wall of the pan 13. While the dry solid material is thus being forced up through the outlet 34, through the reciprocations of the shaft 28, the liquid, such as oil, is being forced out throu h the vents 35 by centrifugal action into t e container 36, whence it is drained oE-through a discharge pipe 3 7. The solid material -is held back, and the liquid'is expressed by being forced under great pressure between the rings 38 which are held in place in a recess rlhe pan 13 is provided with y in the inner wall of the pan 13 by the clamp- -theliquid is confined within the container 36. l .v v

As a simple means of regulating the size of the outlet 34, the collar 43 has teeth 44 on its outer periphery, as well as threads 45 on its inner circumference, which screw on the threads 47 of the clamping-ring 39. This collar 43 is turned by screwing the head`45 down until the yopeningv 46 meshes with the teeth 44, when the wheel 48 is turned, thus turning the collar to the right or left to regulate the size of the outlet 34.

The various moving parts are surrounded byvsuitable'ball-bearings 49, wherever they are neededcas shown, and the lower ends of the toggles 32 are carried in squared blocks i 50 (see Figs. 5 and 6) which have dovetailed sliding connection 51 with the upper end of the shaft 28, and bushings (such as 52) are employed wherever required.

Thus two mechanicalactions are going on simultaneously, namely a compressing, due

to the reciprocation of the central shaft 28 with the head 31 in the receptacle 30, and a centrifugal force due to the rotations of the operating parts, .all of which is mechanical as distinguished from hydraulic or other pressure. This vconstruction described is merely typical; it might, of course, be varied more or less without departure fro-m my invention.

Theremightbe occasions when it `would be desirable to operate this machine without toggles 32,v for example for some materials which do not require great pressure, in which instance it might be advantageous to make the simple alteration of connecting the head 31 directly to the vertical shaft 28, thereby omitting the toggles.
